AgentIndex

Three of four tools involve service selection: find_service (search registry), resolve_data_need (pick best to pay), and get_verified_data (pick + fetch). The boundaries between browsing, recommending, and fetching-while-selecting are subtle and an agent could easily misselect between find_service and resolve_data_need.

All four names follow a consistent verb_noun snake_case pattern (check_trust, find_service, get_verified_data, resolve_data_need). Conventions are uniform and readable throughout.

Four tools is lean but well-targeted for the trust-plus-discovery-plus-fetch workflow. It sits at the thin end, though each tool still maps to a distinct stage of the pipeline.

The surface covers discovery (find_service), trust inspection (check_trust), selection (resolve_data_need), and verified retrieval (get_verified_data), forming a coherent lifecycle. Minor gaps exist, such as listing/browsing the full registry or fetching raw data without trust overhead.
